MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters latent No. 405,756, dated June 25,1889.

Application filed September 15, 1888. Serial No. 285,514. (No model.)

To all whom it may concern.-

Be it known that I, JAMEs H. BAKER, of Savannah, in the county of Andrewand State of Missouri, have invented a new and Improved MechanicalMovement, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved mechanicalmovement which is very simple in construction and effective inoperation, serving for converting a swinging motion into a continuousrotary motion, at the same time avoiding dead-centers.

The invention consists of a wheel provided with a hub having two sets ofratchetteeth standing in opposite directions, collars loosely fitted onthe said hub, pawls fulerumed on the said collars and provided witharms, and a lever connected with the arms of the said pawls.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a face view of the improvement. Fig. 2 is a side elevationof the same with parts broken out. Fig. 3 is a sectional side elevationof the same on the line 20 w of Fig. 1. Fig. is a sectional face View ofthe improvement on the line .1: .11 of Fig. 2, and Fig. 5 is a similarview of the same on the line 3 y of Fig. 2.

The improved mechanical movement A is preferably mounted on a post 13,carrying a fixed shaft C, on which turns loosely a wheel D, connected bya belt E with suitable machinery to be driven. The wheel D is providedwith a hub F, on which are formed two ratchet-wheels G and II, havingtheir teeth standing in opposite directions to each other.

The ratchet-wheels G and II are surrounded by collars I and J,respectively, mounted to turn loosely on the hub F around the saidwheels. The collars I and J are provided at their upper ends with slots1' and J, respectively, in which are fitted the pawls K and L,respectively, adapted to engage the ratchetwheels G and H, respectively.

The pawls K and L L and L are fulcrumed on the pins K and L, secured. inthe collars I and J, respectively, and the said pawls are also providedwith upwardly and outwardly extending arms K K The arms K and L extendto the left and the arms K and L extend to the right and are connectedby the belts N O and N O, respect-ively, with the outer ends of a leverP, mounted to swing on a stud Q, secured to the lower end of the post B.

The wheel D, with its hub F, is held in place on the shaft 0 by a washerR, secured to the outer end of the said shaft 0 by a screw S. The washerR also serves to hold the collars I and J in place on the hub F.

The operation is as follows: hen a swing ing motion is imparted to thelever P and the left end of the said lever passes downward, then thebelt N exerts a pull on the arm K of the pawl K, so that the latterengages the teeth 7 Patent 1. The co1nbination,with a wheel providedwith a hub having two sets of ratchet-teeth standing in oppositedirections, of collars fitted loosely on' the said hub over the saidratchet-teeth, pawls fulcrunied on the said collars and adapted toengage the said ratchetteeth, arms formed on the said pawls andextending outward, and a lever connected with the said arms,substantially as shown and described.

2. The combination,with a wheel provided with a hub having two sets ofratchet-teeth standing in opposite directions, of collars mounted toturn on the said hub and fitting over the said ratchet-teeth, a pawlfulcrumed on each of the said collars and engaging the respectiveratchet-teeth, two arms formed on each of the said pawls and extendingoutward in opposite directions, belts connecting with the outer end ofeach of the said arms, and a lever connected at its ends with the saidbelts, substantially as shown and described.
